Abstract

SCR system comprising a tank for storing an additive, an injector, a pump for conveying the additive from the tank to the injector via an injection line, a primary filter located on the injection line between the tank and the pump and a secondary filter also located on the injection line but between the pump and the injector, said system further comprising a particle trap located between both filters.
